Which of the following statements in incorrect ?

Options

A. Testis and ovary function as a primary sex organ as well as endocrine gland
B. Ovaries are located in thoracic cavity of females
C. Ovary produces ovum, 2 groups of steroid hormones (estrogen and progesterone)
D. Ovary is composed of ovarian follicles and stromal tissue

Answer

To determine which statement is incorrect, we will analyze the provided information step by step.

### Step 1: Identify the Functions of Testes and Ovaries
- Testes and ovaries are known as primary sex organs because they are responsible for producing gametes (sperm in males and eggs in females).
- They also function as endocrine glands, meaning they synthesize and secrete hormones that regulate various bodily functions.

**Hint for Step 1:** Remember that primary sex organs also have endocrine functions.

### Step 2: Understand the Gametogenesis Process
- In the testes, the process of sperm production is called spermatogenesis.
- In the ovaries, the process of egg production is called oogenesis.

**Hint for Step 2:** Focus on the terms "spermatogenesis" and "oogenesis" as they relate to the functions of the testes and ovaries.

### Step 3: Identify the Hormones Produced
- The testes produce the hormone testosterone.
- The ovaries produce two main hormones: estrogen and progesterone.

**Hint for Step 3:** Recall the specific hormones associated with each organ.

### Step 4: Analyze the Location of Ovaries
- The transcript mentions that "ovaries are located in the thoracic cavity," which is incorrect.
- Ovaries are actually located in the pelvic cavity, not the thoracic cavity.

**Hint for Step 4:** Consider the anatomical position of the ovaries relative to other organs.

### Step 5: Evaluate the Composition of Ovaries
- The ovaries are composed of ovarian follicles and stromal tissue, which is a correct statement.

**Hint for Step 5:** Think about the structure of the ovaries and what types of tissues they contain.

### Conclusion
Based on the analysis, the incorrect statement is: "Ovaries are located in the thoracic cavity." The correct location of the ovaries is in the pelvic cavity.

### Final Answer
The incorrect statement is: "Ovaries are located in the thoracic cavity."
